After David Ortiz was held out of Saturday's lineup with calf tightness, Mike Carp was scratched with lower back tightness.

Carp was supposed to play first base, allowing Mike Napoli to act as the designated hitter. Instead, Daniel Nava moved from left field to first base and Jonny Gomes took Carp's spot in the lineup.

The Red Sox will have a short bench for Saturday's game against the Milwaukee Brewers. Without Ortiz or Carp, Will Middlebrooks and backup catcher David Ross are the only two position players available.

Carp is 2-for-6 with a double so far this season, playing only against right-handed pitchers.
